Persi Diaconis - a Stanford mathematician who used to be a professional magician - asked a simple question: how many times do you have to shuffle a deck for it to become truly random?
turns out there's an exact answer. not a gut feeling, a theorem: seven. fewer than that and the deck only looks mixed - a sharp person at the table can beat you, because some of the order is still alive.
and the twist: the answer depends on how you shuffle. one common method takes 7 times; another takes ten thousand. a gap most card players never suspect.
at 00:19 he names the number, and at 04:33 he derives it with almost no formulas - using a single card slowly rising to the top.
9 minutes on how much math hides inside an ordinary flick of the hands.

अजं शाश्वतं कारणं कारणानां
शिवं केवलं भासकं भासकानाम् ।
तुरीयं तमःपारमाद्यन्तहीनं
प्रपद्ये परं पावनं द्वैतहीनम् ॥
Bruce Lee’s file is part of the immigration records at the National Archives in San Bruno, which could soon close. I explain why these artifacts are important for the Bay Area’s Chinese American community in my new @sfc_opinions@sfchronicle column/newsletter. 1/2
Missouri police are searching for a man accused of tearing gutters off a church on the Fourth of July while wearing a stars-and-stripes outfit with "One Nation Under God" printed on the back.
Surveillance video shows the "less than patriotic" man, as police described him, ripping the gutters from the church in Fenton, stomping on them and carrying them away.
you think the guy out-shipping you
opened some smarter Claude
he didn't
same model, same twenty bucks, same blank box
he just stopped starting from zero
he wrote the job down once, in a file
now it knows his voice,
his standards, his last twenty calls,
before he types a word
you're still re-explaining yourself
to a genius with amnesia
